Abstract

The invention provides an inertial device residual moment measurement device and method and belongs to the technical field of detection. The device comprises an on-platform system, an off-platform system and a wireless transmission system, wherein the on-platform system and the off-platform system are wirelessly connected through the wireless transmission system; the off-platform system comprisesan off-platform data acquisition and processing system, a server and a cabinet box; and the on-platform system comprises a power supply and gas supply system, an inertial execution mechanism control system, an inertial execution mechanism to-be-measured product, an on-platform data acquisition and processing system, a residual moment testing system, a vibration isolation and support system and a vacuum control system, and the residual moment testing system comprises an air flotation platform, air feet and a high-precision sensing device. On-orbit work of a satellite platform can be simulated,a space mechanical environment for simulation is provided, residual moment is output in real time, and the device and the method are applicable to direct measurement of multiple inertial devices and are smaller in calculation of numerical values, higher in accuracy and perfect in theory.

Description

technical field [0001] The invention relates to a device and method for measuring the residual moment of an inertial device, belonging to the technical field of detection. Background technique [0002] With the development of my country's aerospace level, the requirements for the observation accuracy of modern high-level spacecraft for payloads have been greatly improved compared with the past. The research shows that during the working process of the inertial actuator, due to factors such as the inability to completely eliminate the dynamic unbalance, the electromagnetic field and the non-ideal characteristics of the shaft system, there will be a residual moment with a wide frequency distribution. This residual moment is usually small in magnitude, but it will affect the observation accuracy of the payload, and even cause the satellite platform to vibrate. At present, in the test for inertial actuators, there is no means to test the residual moments of the rotating parts a...
